SPINNING-FRAME FOR FLAX, HEMP, J UTE, AND OTHER FIBERS.

Specification of Letters IPatent.

Patented May16, 191s.

Application filed March 14, 1913. Serial No. 754,342.

To all whom it may concern Be it known that I, Gnoa'on SHAW, a Britishsubject, residing at Leeds, county of York, England, have inventedcertain new .and 'useful Improvements in Spinning- Frames for Flax,Hemp, Jute, and other Fibers, of which the following is a specification.i

This invention relates to machines for' spinning flax, hemp, jute andsimilar fibers to which a cop or bobbin building motion is applied. Itis customary in these machines to raise the bobbin building rail by acam acting through a long connecting chain and link to rotate thelifting shaft in one direction, but to allow the rail to fall by its ownexcess weight.

The object of this invention is to mount the camand a rack in such a wayas to operate or rotate the lifting shaft in both directions and therebycompletely control the movement of the builder rail in both the up wardand downward direction and by this means to obtain a quick traverse anda cross wind of the yarn on the bobbin. I

The invention consists essentially in arranging the building cam to actdirectly on a sliding raclvto move it positively in both directions,which rack in turnmeshes directly with'a'pinion on the lifting shaft ofthe machine to rotate it first in one direction and then in the reversedirection to impart a positive motion both up and down to the spindlerail.

The invention will be fully described with reference to the accompanyingdrawings.

Figure 1. is a transverse sectional elevation of part of a revolvingring and centrifugal presser spinning frame having the invention appliedthereto. Fig. 2. is a part end elevation of same. Fig. 1s a sectionalplant at one end of the machine.

The machine illustrated'is of the newest type of construction forjutespinning with crawing rollers A, revolving ring B, centrifugal presserl), spindle C and vertically reciprocating spindle rail D, said railbeing raised by vertical racks E meshing with pinions e placed atintervals on the lifting shaft F of the machine. however, applicable toother ordinary types of spinning frames.

On one end of the lifting shaft F a sec ond pinion G is affixed. withwhich a re ciprocating sliding rack H meshes to give a The inventionis,..

reciprocating rotary movement to the lifting shaft F.

The reciprocatingslidingrack H is preferably placed horizontal and ismounted in a guide casing h in the framing at one end of the machine,the said casing completely inclosing the rack, as will be understoodfrom Figs. .2 and 3. The teeth of the reciprocating sliding rack H meshwith the pinion G on the lifting shaft F. "To the reciprocating rack Htwo rollers k andh? are fitted on studs h secured to the rack andproject laterally from the same through slots formed in the innerside ofthe casing k. The lifting cam K is mounted to rotate between the tworollers 71, and if and is in conrack H first in one direction and thenin the reverse direction. By this means a doubleacting movement isimparted to the rack and by it to the sp ndles, which movement issensitive and positive lnboth directions.

' tact with both to impart movement to "the v The cam K is driven at asuitable speed from thefront delivery roller of the machine, or from anyother convenient part by gear It is of heart or other shape togive asimilar movement to the rack H, in both directions and shaped to preventa dwell of the rack at either end. The rollers h and k with which thecam contacts are mounted on studs k which'are readily adjusted tomaintain them in close contact with the periphery of the cam.-

I preferably suspend balanced weights WV to the lifter shaft to aboutcounterbalance the weight of the spindle rails.

By thisarrangement I am' able to impart a long lift to the builderrails, and to drive same at a quick up and down speed, so as to producea cross wound bobbin, and one which may be spun on the bare spindle, oron paper tubes, or on headless wooden bobbins.

WhatI claim as my invention and desire to protect by Letters Patentis 1. In a spinning frame, the combination with a vertical spindle, arail carried thereby, a reciproeatory I vertical rack' bar to which therail is directly connected, a horizontal lifting shaft and a liftingpinion pletely housed in said casing and movable in a horizontal planetherein, one end of said I ing a stationary axis and meshing with saidrack bars whereby the vertical rack bar is reciprocated, guide means forsaid horizontally reciprocatory bar comprising a horizontally extendingcasing having its inner side wall longitudinally slotted, means foractuating said horizontally reciprocatory bar and means extending fromsaid lastmentioned bar and in constant engagement with said actuatingmeans.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. 1 GEORGE SHAW.
